Anyone know how to debug this intrusion.

[DWHS.net]

Hello,

On a test server we managed to get it attacked and hacked with felonious information.

We know are going to try to debug it without re-installing redhat.

Any ideas on how to dig out the trojan horse or whatever the hacker did in this folder?

The logs where re-directed to dev/null so there is no record of what was done.

Maybe a good tool that can find a trojan and debug it?

Here is the hack from user rpm:

We are new to trojan debugging and will post any useful information if it arises. This is experimental so any suggestions are welcome.

Thanks,
